We were out n our boat today and after well all wakeboarded, till we could no more, the lil ones went tubin, but with our racks, when we go over wakes, the racks slip, and eventully start banging up against the tower, we usally take them out once it starts slipin.

Any ideas of how we could prevent this problem? any advice well be nice. thnx!

tighten them like crazy, my wake designs racks did the same thing, and i just kept tightening them down every time the slipped(after pushing them back up), make sure you ahve a rubber insert between the metal of the mount and the tower. This was only a problem on the trips up and down the river near the open bay where there was lots of wind chop and the boat was bangin around a little.
